Any OpenCV-like C/C++ library for Audio processing? -


is there more out there, resembles (in spirit) opencv, processing audio , deriving intelligence ? capabilities range from:-

  1. multiplatform audio capture , audio playback
  2. dsp - audio filters
  3. tone detection
  4. tonal property analysis
  5. tone synthesis (various standard waveforms)
  6. recognition given recognition corpus , model (e.g. determine musical instruments, beats, human speech etc.) -- potentially use other open-source projects actual recognition part (sphinx)
  7. speech / music synthesis -- again using other open-source projects (festival)

it fine if library works on raw audio s.t. format/encoding conversion external issues handled other existing libraries (s.a. ffmpeg).

i not expert in field, need use such api, , wondering if such libraries exist, choice of terms determine capabilities not best, experts might edit question.

for audio capture , playback, portaudio comes mind.

for audio processing, stk looks promising.

have @ related question too: can recommend decent dsp/speech library in c++?

i recommend these 3 libs:

  1. very easy use , friendly general signal processing aquila-dsp

  2. strong lib audio signal processing although hard use , it's big , complicated beginners: clam project

  3. another 1 have no experience it, worth considering though. tspl

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
